Specification of Letters Patent.

Patented Dec. 14, 1915.

Application led September 10, 1913. Serial No. 789,107.

To all whom t may concern.'

Be it known that I, CHARLES A. KAISER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Electromagnets, of which the following is a specification.

My invention relates to improvements in apparatus for treating the body by electromagnets, the object of the invention being to provide an apparatus of this character which will, through the improved magnets, impart heat, vibration, and magnetism to various parts of the body to heal various. diseases.

QA further object is to provide a chair with improved attachments, said chair at the back, seat, sides, leg rests, and foot rest containimf.r electro-magnets and provide an improved head piece and improved knee pieces, all containing electro-magnets so that the different parts of the body may be treated.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in side elevation illustrating my improved chair equipped with my improved attachments. Fig. 2 is a View in front elevation of Fig. 1. Fig. 3 is a perspective View of the head piece. Fig. 4 is a view in side elevation of one of the knee pieces. Fig. 5 is a view in section on an enlarged scale through one of the electro-magnets, and Fig. 6 is an end view of the magnet shown in Fig. 5.

1 represents a chair having a seat portion 2, a back 3, sides 4 constituting the arms, a foot rest 5, and a leg rest 6 connecting the seat with the foot rest.

The chair may be made in various ways so that it may be adjusted to allow the patient to assume a comfortable position andin the back, seat, and leg rest, I preferably provide ordinary caning as indicated at 7, but do not limit myself in this particular.

To the upper end of the back 3 of the chair, I removably connect my improved -head piece 8. This head piece is shown in perspective in Fig. 3, and comprises a U- shaped horizontal frame 9 connected at opposite sides by an inverted U-shaped vertical frame 10. These frames each comprise strips of metal spaced apart and having between them my improved electro-magnets 11. While I do not limit myself to any particular number of such magnets, I preferably provide live in each of the frames.

The horizontal frame 9 is provided with sleeves 12 in which hooks 13 are adjustably secured by set screws 14, and these hooks 13 are adapted to be positioned in recesses in the back of the chair to hold the head piece in place.

At the forward edge of the seat 2, I support my improved knee pieces 15. These ee pieces are curved in the arc of a circle and comprise metal straps spaced apart and supporting electro-magnets 11. The knee pieces are connected by a rod 16 which is adjustably secured by sleeves 17, and set screws 18, with the free ends of arms 19.

The arms 19 are adjustably connected at their ends by bolts 20. and wing nuts 21 with arm sections 22 adapted to be positioned in sockets in the seat portion of the chair. By reason of this construction the knee pieces may be properly positioned over the knees of the patient.

To the back 3, seat 2, sides or arms 4, leg rests 6 and foot rest 5, I secure metal bars or frames 23 supporting electro-magnet 11. I give all of these electro-magnets the same reference numeral because they are precisely alike in construction, one of which being shown in longitudinal section in Fig. 5. Assuming this section to be taken on the line 5 5 of Fig. 3, the bolt 24 constituting the core of the magnet is projected through the outer strip 9, and is secured by a nut 25.

Between the magnet and the strip 9, and confined between nuts 26, is a disk 27 preferably of aluminum which is utilized for its repulsive qualities to increase the vibrations of the magnet.

It is to be understood that the magnets are connected in circuit with an alternating current, so that the rapid pulsations of the current cause vibrations as well as magnetic discharges.

The magnet 11 around the bolt or core is provided with a sleeve 29 of insulation, and at opposite ends of the sleeve with relatively large laminations 30. Around the sleeve 29, relatively small laminations 31 are located, and around these laminations, suitably magnet.- grzed, they impartrapiol-vibrations'to the spaced therefrom, 'is the 'Winding 32 ot the When thesel magnets vbecome enervvired in any Way, but preferably vin series and controlled by any suitable switch mechanism. ln connection with the chair, hovvever, .'l preferably provide at one side thereof, a box 33 containing electric svvitches 3a and electric lights 35, so that the operi et tti

.ator can readily control' the circuits and observe by the lights just vvhichsets or" magnets are energized.

'.By arranging the magnets forth, the various parts of the treated.

By reference .to Fig. .2, it vvill be noted that the back 3 ol:b the chair hasV its magnets arranged so asto etlect the lovver or the upper portion ot the back, and it will alsobe noted that the magnets are preferably arranged in groups of :ve and ten,but ot course this number is not essential.

The patient .assumesv a natural position on the chair and it the head is to receive treatment, the head piece 8 is positioned on the chair as shown, and the. head of the patient is located inside of both the trames 9 and 10. The knee pieces l5 Will rest directly over theV knees 'ot the-patient, andthe head piece and lknee pieces may be detached if not desired. 1'

lll/'hen the magnets are excited by an al-v as above set body vmay be ternating current, lEoucault or leddy cnrrents are established in the repulsive disks. ttl,

A' vibration and increased temperature of thel disk is thus produced and this condition,`together with the magnetic eld produced has a beneficial ed'ect upon the body when brought into proximity thereto.

Various slight changes might be made in the general form and` arrangement of parts described Without departing `from my invention, and hence ll do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.

Having thus vdescribed my invention, Whatjll claim as nevvand desire to secure by Letters Patent is:
